Carney said Supreme Court Chief Justice John Roberts will administer the oath of office just before noon Sunday, the time required by the Constitution.

Mr. Obama's family will attend along with a few reporters, and Obama isn't expected to make a speech.

The Constitution requires that the president be sworn in on Jan. 20, but because that falls on a Sunday this year, Mr. Obama will have two ceremonies, one on Sunday and a larger, public ceremony on Monday, followed by a parade and inaugural balls.

Vice President Joe Biden will be sworn in during a separate ceremony Sunday morning at the Naval Observatory.
